Abstract
We present an 18-year-old male patient who presented with a 16 cm testicular tumor alongside multiple lesions in the lungs, right pelvis with involvement of the ischio/pubic bone, and enlarged pelvic lymph nodes on imaging, suspicious for metastatic disease. Histologic and immunohistochemical examinations revealed an embryonic type neuroectodermal tumor (somatic-type malignancy, 10%) arising in a malignant mixed germ cell tumor composed of teratoma (50%), embryonal carcinoma (10%) and yolk sac tumor (30%). After treatment with chemotherapy and radiation, repeat imaging demonstrated a right pelvic sidewall mass that decreased in size from 40 mm at 11 months after the initial diagnosis to 18 mm at 22 months after the initial diagnosis. A right pelvis medial thigh wall mass that had a lytic bone component showed a slight increase in size from 151 mm at 11 months after the initial diagnosis to 154 mm at 22 months after the diagnosis. On biopsies performed at 3, 10, and 26 months after the initial diagnosis, this lytic lesion consistently demonstrated a neoplasm composed of low-grade neuroglial differentiation. This is the first case in the medical literature where a residual malignant germ cell tumor consisting of low-grade neuroglial neoplasm is in a site that is not amenable to resection without significant morbidity. The tumor initially regressed with the traditional first-line chemo-radiotherapy regimen but regrew and stabilized with a second regimen of chemotherapy. The clinical course of this case invites consideration for an active surveillance approach in cases with similar characteristics.

Abstract
Early stage nonseminomatous germ cell tumor (NSGCT) remains a treatable disease, with stage I cancer specific survival exceeding 95%. Using a risk-adapted approach; active surveillance (AS), adjuvant chemotherapy, and retroperitoneal lymph node dissection (RPLND) all options for treatment; with surveillance being increasingly used. With persistently elevated markers (stage IS), chemotherapy remains the hallmark of treatment. Management of stage II NSGCT varies based on status of tumor markers. With negative markers, both induction chemotherapy and upfront RPLND remain options. Management of a residual mass <1 cm after chemotherapy remains controversial, with AS and nerve-sparing RPLND considered options. The development of miR-371a-3p microRNA shows promise a novel biomarker for testicular cancer (GCT). Despite controversies in management, cures for NSGCT are achievable in 95-99% of patients.

Abstract
46, XY pure gonadal dysgenesis (PGD) is characterized as a female phenotype with strip-like gonads, which has a high tendency to develop into gonadal tumors. Somatic-type malignancies of germ cell tumors (SMs of GCTs) refer to the presence of malignant non-germ cell histologies admixed with GCTs, which are usually chemoresistant and indicate poor prognosis. This case report aimed to analyze the special histological type of GCTs and the importance of salvage surgery in the treatment of refractory GCTs. We report a unique case of gonadal yolk sac tumor (YST) transformed into SMs in a patient with 46, XY PGD. This 18-year-old woman underwent laparoscopic pelvic tumor resection, considered her first surgery, 2 years ago, and pathology revealed YST with initial alpha-fetoprotein (AFP) level measuring >3,000 ng/mL. She underwent seven cycles of chemotherapy, and the AFP level decreased to within a normal range after the second cycle. However, a computed tomography scan after the seventh cycle revealed abdominal and pelvic metastases, and vaginal bleeding was continuously observed. Laparoscopic exploration and laparotomy with tumor subtotal resection were performed. A pathology report showed SMs (sarcoma) derived from YST. Whole exome sequencing demonstrated that the main somatic mutation was a non-synonymous mutation of KRAS (c.182A>G), and this result did not show any indications for targeted drugs. She received three cycles of PEI (cisplatin, etoposide, and ifosfamide) chemotherapy but showed no response. She refused to undergo further treatment and has been alive with the disease for 7 months. This suggests that SMs may be one of the reasons for chemoresistance of refractory GCTs, and salvage surgery may be one of the most effective treatments for this patient. Targeted therapy may be a new choice for chemoresistant GCTs, but drug selection must be based on gene sequencing, and its efficacy still needs to be verified by further study.

Abstract
Testicular cancer is a rare urological malignancy with high cure rate. The development of highly effective systemic treatment regimens along with advances in surgical treatment of advanced disease has led to continued improvement in outcomes. Patients with testicular cancer who are treated following the treatment guideline mostly achieved high quality of life and long-term survival. However, patients who were identified as having non-guideline directed care were at significantly higher risk of relapse. In this book chapter, we introduce in depth the modern management of testicular cancer, including diagnosis, staging and risk stratification, treatment strategies of seminoma and non-seminoma germ cell tumors, follow-up protocols, and salvage treatment for disease relapse. We also review new studies and updates on medical and surgical management of advanced testicular cancer.

Pure Testicular Seminoma Relapsing Late with Somatic Type Malignancy. Case Rep Oncol Med 2017; 2017:2457023.

Abstract
Background. Somatic type malignancy (STM) occurs in 2% of all germ cell tumours (GCTs). The prognosis is unfavourable and the origin is poorly understood. Pathogenetic hypotheses involve direct transformation of teratoma, origin from totipotent cancer cells, or derivation from yolk sac tumour elements. Case Presentation. A 31-year-old patient was cured from testicular seminoma clinical stage IIc by orchiectomy and cisplatin-based chemotherapy. Nine years later, he experienced a late relapse with a mass sized 5 × 6 cm located at the former metastatic site. As no remission occurred after chemotherapy with three cycles of cisplatin, ifosfamide and etoposide, the mass was surgically resected. Histologically, the specimen consisted of neurofibroma with areas of malignant peripheral nerve sheath tumour and spots with mature bone formation. FISH analysis disclosed isochromosome 12p in the majority of evaluated cells suggesting somatic type malignancy (STM) of GCT. The patient is well 1 year after surgery. Conclusion. The pathogenesis of this STM remains enigmatic. The origin from GCT was evidenced by documentation of isochromosome 12p. Unrecognized teratomatous elements in the primary and totipotent cancer cells surviving the first chemotherapy could be hypothesized to represent the origin. STM developing from seminoma cells would be another novel hypothesis.

Abstract
CONTEXT Some controversy still exists regarding the management of testis cancer following chemotherapy for disseminated disease. OBJECTIVE To review the available literature concerning the management of postchemotherapy testis cancer. EVIDENCE ACQUISITION A Medline search was conducted to identify original and review articles, as well as guidelines addressing the management of testis cancer following first-line chemotherapy. Keywords included germ cell tumor, testis cancer, retroperitoneal lymph node dissection, and chemotherapy. The most relevant articles were critically reviewed with the consensus of all the collaborative authors, who have expertise in the management of germ cell tumors (GCTs). EVIDENCE SYNTHESIS Approximately one-third of patients who undergo chemotherapy for metastatic GCTs have residual retroperitoneal disease. All patients with residual masses ≥1cm after chemotherapy for nonseminomatous GCTs should undergo postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) because of the risk of mature teratoma in 40-45% of cases and of viable GCT in 10-15% of cases. Patients who obtain a complete serologic remission and radiographic residual <1 cm after chemotherapy have a 6-9% risk of relapse. Patients with a completely resected teratoma in only the PC-RPLND specimen have a >90% chance of cure, while patients with viable GCTs should be considered for additional therapy, depending on the percentage of viable tumor. In patients with disseminated seminoma, postchemotherapy masses <3cm may be safely observed, while patients with masses >3 cm should be evaluated with positron emission tomography (PET)/computed tomography 2 mo after completion of chemotherapy, with very selective administration of PC-RPLND. Late relapse occurring >2 yr after chemotherapy is rare, and surgery remains the mainstay of therapy in cases of resectable masses independent of tumor markers. There is still controversy on whether high-dose chemotherapy confers a survival benefit compared with conventional-dose chemotherapy in the salvage setting. Surgery should always be considered for resectable masses following salvage therapies or in chemoresistant disease to maximize chance of cure. CONCLUSIONS Patients with advanced GCTs can achieve long-term disease-free survival when chemotherapy is combined with expert and judicious resection of residual disease. PC-RPLND is recommended for residual masses >1cm identified on postchemotherapy imaging in nonseminomatous GCT and possibly for PET-positive residual disease ≥3cm in treated seminomas.

Abstract
Recognition of the therapeutic role of retroperitoneal lymph node dissection (RPLND) in the setting of testicular germ cell tumors (GCTs) is of utmost importance. Although the histologic findings of RPLND provide diagnostic and prognostic information, the adequacy of initial RPLND is an independent predictor of clinical outcome. Despite the advent of effective cisplatin-based chemotherapy for testicular GCTs, patients who have undergone suboptimal surgery at the time of initial RPLND are compromised. Despite the initial enthusiasm surrounding anatomic mapping studies, the use of modified RPLND templates has the potential to leave a significant number of patients with unresected retroperitoneal disease. Teratomatous elements are particularly common. Patients with retroperitoneal relapse following initial RPLND should be treated with reoperative RPLND and chemotherapy and can expect long term survival rates nearing 70% when treated in tertiary centers by experienced surgeons.

Abstract
Currently, the outcome of patients with intermediate-and poor-risk germ cell tumors at diagnosis is optimized by the use of risk-appropriate chemotherapy and post-chemotherapy surgical resection of residual masses. Currently, there is no role for high-dose chemotherapy in the first-line setting. Patients who progress on first-line chemotherapy or who relapse after an initial complete response also have a poor prognosis. In the setting of early relapse, the standard approach at most centers is conventional-dose, ifosfamide-based regimens and post-chemotherapy resection of residual masses. The treatment of patients with late relapse is complete surgical resection whenever feasible. Salvage chemotherapy for late relapse may be used prior to surgery in patients where a complete resection is not feasible. A complete surgical resection of all residual sites of disease after chemotherapy is critical for the prevention of relapse and the long-term survival of patients with advanced germ cell tumors.

Abstract
PURPOSE We assessed whether imaging α(v)β(3) integrin could distinguish mature teratoma from necrosis in human non-seminomatous germ cell tumour (NSGCT) post-chemotherapy residual masses. METHODS Human embryonal carcinoma xenografts (six/rat) were untreated (controls) or treated to form mature teratomas with low-dose cisplatin and all-trans retinoic acid (ATRA) over a period of 8 weeks. In another group, necrosis was induced in xenografts with high-dose cisplatin plus etoposide (two cycles). (18)F-Fluorodeoxyglucose ((18)F-FDG) small animal positron emission tomography (SA PET) imaging was performed in three rats (one control and two treated for 4 and 8 weeks with cisplatin+ATRA). Imaging of α(v)β(3) expression was performed in six rats bearing mature teratomas and two rats with necrotic lesions on a microSPECT/CT device after injection of the tracer [(99m)Tc]HYNIC-RGD [6-hydrazinonicotinic acid conjugated to cyclo(Arg-Gly-Asp-D-Phe-Lys)]. Correlative immunohistochemistry studies of human and mouse α(v)β(3) expression were performed. RESULTS Cisplatin+ATRA induced differentiation of the xenografts. After 8 weeks, some glandular structures and mesenchymal cells were visible; in contrast, control tumours showed undifferentiated tissues. SA PET imaging showed that mature teratoma had very low avidity for (18)F-FDG [mean standardised uptake value (SUV(mean)) = 0.48 ± 0.05] compared to untreated embryonal carcinoma (SUV(mean) = 0.92 ± 0.13) (p = 0.005). α(v)β(3) imaging accurately distinguished mature teratoma (tumour to muscle ratio = 4.29 ± 1.57) from necrosis (tumour to muscle ratio = 1.3 ± 0.26) (p = 0.0002). Immunohistochemistry studies showed that α(v)β(3) integrin expression was strong in the glandular structures of mature teratoma lesions and negative in host stroma. CONCLUSION Imaging α(v)β(3) integrin accurately distinguished mature teratoma from necrosis following cisplatin-based treatment in human NSGCT xenografts.

Abstract
OBJECTIVE The presence of teratoma in the primary orchiectomy specimen creates controversies for subsequent management. Although predominant teratoma is less likely to metastasize, teratoma in the retroperitoneum may be less amenable to chemotherapy. In order to elucidate the issues about teratoma in the primary tumor, we reviewed differences between primary retroperitoneal lymph node dissection (P-RPLND) vs. post-chemotherapy RPLND (PC-RPLND) in patients with teratoma at orchiectomy. MATERIALS AND METHODS Patients who had undergone RPLND at our institution from 2001 to 2008 were identified, and clinical charts reviewed. Eighty-three patients with teratoma at orchiectomy were identified and perioperative data were obtained. RESULTS Of the 83 patients with teratoma at orchiectomy who underwent RPLND, 44 (53%) and 39 (47%) underwent primary and PC-RPLND, respectively. Median follow-up was 1.4 years. Of the 83 patients with primary teratoma at orchiectomy, there were 7 (8%) patients with pure teratoma and 76 (92%) patients with mixed histology. Of the patients with mixed histology, 72 (87%) patients had embryonal carcinoma and 36 (43%) had LVI. There were 19 (43%) positive lymph nodes for P-RPLND, of which 13 (30%) contained teratoma. For the PC-RPLND group, 30 (77%) of lymph nodes were positive, of which 28 (72%) contained teratoma. There were 3 (4%) recurrences overall, all of which recurred in the PC-RPLND group. There were 11 (13%) perioperative complications total. There were no deaths in either group. CONCLUSIONS Patients with teratoma at orchiectomy were associated with other high risk features and are at significant risk for metastatic disease. Patients with post-chemotherapy retroperitoneal findings are at significant risk for viable GCT and/or teratoma and should undergo PC-RPLND.

Abstract
PURPOSE Late relapse (LR) of germ cell tumor (GCT) is a well recognized entity associated with poor survival. We report on our experience with LR and determine predictors of survival. PATIENTS AND METHODS From 1990 to 2004, 75 patients were managed for LR of GCT at our institution. Clinical and pathologic parameters were reviewed. Estimates of cancer-specific survival were generated using the Kaplan-Meier method, and a Cox proportional hazards model was used to assess potential predictors of outcome. RESULTS The median time to LR was 6.9 years (range, 2.1 to 37.7 years). Overall, 56 patients (75%) had LR in the retroperitoneum, including 25 (93%) of 27 patients initially managed without retroperitoneal lymph node dissection. The 5-year cancer-specific survival (CSS) was 60% (95% CI, 46% to 71%). Patients who underwent complete surgical resection at time of LR (n = 45) had a 5-year CSS of 79% versus 36% for patients without complete resection (n = 30; P < .0001). The 5-year CSS for chemotherapy-naive patients was significantly greater than patients with a prior history of chemotherapy as part of their initial management (5-year CSS, 93% v 49%, respectively). In multivariable analysis of pretreatment parameters available at the time of LR, the presence of symptoms (hazard ratio [HR] = 4.9) and multifocal disease (HR = 3.0) were associated with an inferior CSS. CONCLUSION The data suggest that meticulous control of the retroperitoneum is critical to prevent LR in the retroperitoneum. In multivariable analysis, patients with a symptomatic presentation and those with multifocal disease have a significantly decreased survival. Survival is greatly improved if complete surgical excision of disease is attained.

Abstract
In this paper we review clinical and genetic aspects of testicular germ cell tumours (TGCTs). TGCT is the most common type of malignant disorder in men aged 1540 years. Its incidence has increased sharply in recent years. Fortunately, survival of patients with TGCT has improved enormously, which can chiefly be attributed to the cisplatin-based polychemotherapy that was introduced in the nineteen eighties to treat patients with metastasized TGCT. In addition, new strategies have been developed in the surgical approach to metastasized/non-metastasized TGCT and alterations have been made to the radiotherapy technique and radiation dose for seminoma. Family history of TGCT is among the strongest risk factors for this tumour type. Although this fact and others suggest the existence of genetic predisposition to develop TGCT, no germline mutations conferring high risk of developing TGCT have been identified so far. A small deletion, referred to as gr/gr, identified on the Y chromosome is probably associated with only a modest increase in TGCT risk, and linkage of familial TGCT to the Xq27 region has not been confirmed yet. Whether highly penetrant TGCT-predisposing mutations truly exist or familial clustering of TGCT can be explained by combinations of weak predispositions, shared in utero or postnatal risks factors and coincidental somatic mutations is an intriguing puzzle, still waiting to be solved.

Abstract
AIMS To identify clinicopathological features and outcomes in patients with late relapse (LR) of testicular germ cell tumours (GCTs) in order to guide follow-up policy. MATERIALS AND METHODS The Edinburgh Cancer Centre (ECC) database identified all patients diagnosed with testicular GCT between 1988 and 2002. Of 703 patients, six relapsed more than 24 months after their initial treatment. A retrospective casenote review was performed to extract clinical, pathological, treatment and outcome data. RESULTS Six patients (0.85%) underwent late relapse. All patients presented initially with stage I disease and five were classified as good risk (International Germ Cell Consensus Classification, IGCCC). Median time to LR was 31 months. Two patients had previously relapsed less than 24 months from initial diagnosis. Markers at the time of relapse were normal in all patients. In all cases of late relapse disease was confined to axial lymphadenopathy. Three patients were treated with chemotherapy alone, two patients underwent surgical resection and one patient received combined treatment. All patients obtained a complete response and all remain disease free with a median follow-up of 52 months. CONCLUSIONS The incidence of late relapse in this series is low. Chemo-naive patients with LR were successfully salvaged with chemotherapy alone and patients previously exposed to cisplatin-based chemotherapy were salvaged with complete surgical excision. The optimal length of follow-up in patients with testicular germ cell tumours is not known and practice varies widely. In this cohort of 703 patients, only one patient who relapsed was picked up by additional clinic follow-up between 5 and 10 years. Thus, on the basis of this small series, the authors suggest that follow-up after five years may not be justified.

Abstract
Although RPLND is both a diagnostic and therapeutic procedure, it must be performed with therapeutic intent. Adequacy of initial RPLND is a prognostic variable for clinical outcome. Effective cisplatin-based chemotherapy will not reliably compensate for suboptimal initial surgery. Many patients undergoing either primary RPLND or PC-RPLND will have unresected extratemplate disease if modified templates are used. Anatomic mapping studies, which provided the basis for modified templates, have significant limitations. Teratomatous elements are often found in the retroperitoneum of patients requiring reoperative surgery, which can be performed with acceptable morbidity in tertiary centers with experienced surgeons. The integration of chemotherapy and reoperative surgery can result in survival rates of almost 70% in patients with retroperitoneal relapse after initial suboptimal RPLND.

Abstract
Late relapses of malignant germ cell tumors (MGCTs) are rare and occur, by definition, 2 years or later after successful treatment. They represent a major challenge of today's treatment of MGCTs. Because of the rarity and heterogeneity of late relapses, many aspects of their main characteristics remain obscure. We present relevant literature on relapsing MGCTs to highlight the following issues: incidence, impact of initial treatment on the subsequent risk of late relapse, treatment, and survival. In a pooled analysis, the incidence is 1.4% and 3.2% in seminoma and nonseminoma patients, respectively. The predominant site of relapse is the retroperitoneal space in both histologic types. The initial treatment appears to be important for the risk and localization of late relapses. The treatment of late relapses should be based on a representative presalvage biopsy and includes radical surgery and salvage chemotherapy in most cases. Five-year cancer-specific survival is above 50% in the recent large series and reaches 100% in case of single-site teratoma. Diagnosis and treatment of late-relapsing MGCT patients is challenging and should be performed in experienced centers only. Referral of late-relapsing patients to high-volume institutions ensures the best chances of cure and enables increasing understanding of tumor biology and the clinical course of these patients.

Abstract
PURPOSE To determine the role of RPLND for residual masses following chemotherapy in patients with non-seminomatous germ cell tumors (NSGCT) stage T1N2 and T1N3 (IIB and IIC). MATERIALS AND METHODS We have preformed retrospective analysis of 11 patients who underwent RPLND for residual masses following chemotherapy in an oncologic reference center between January 1997 and December 2002. All patients harbored either pure nonseminomatous or mixed tumors in the testis tissue and had undergone 4 cycles of primary chemotherapy with bleomycin, etoposide and cisplatin. The residual masses were assessed by abdominal computed tomography preoperatively. RESULTS There were perioperative complications in 3 cases owing to vascular iatrogenic lesion. One of who died in the early postoperative period due to extensive iliac thrombosis. The other 2 patients had an inferior vena cava injury owing to the difficulty in removing the attached lymph nodes. The injuries were repaired by continuous suture with Prolene 5-0. All patients had tumors in the final pathological report and were referred to other 2 cycles of chemotherapy with the same drugs. Seven patients (63.3%) had complete response and remained free of the disease in a mean follow up of 38.3 months (ranging from 12 to 72). The remaining 3 patients had disease progression, 2 of which died 6 and 12 months after surgery, respectively, and one patient missed the follow-up after salvage chemotherapy. CONCLUSION Retroperitoneal lymph node dissection for residual masses after chemotherapy is a high-morbidity procedure, even by experienced surgeons, although it remains an efficient modality of treatment in advanced germ cell carcinoma. The high frequency of tumor found in the RPLFN following chemotherapy might have been caused by the small number of patients in this study.

Abstract
Despite continued refinement in terms of technique and the integration of retroperitoneal lymph node dissection (RPLND) in the management of patients with testicular cancer, RPLND remains an essential component in the ultimate cure of these patients. The failure to eradicate all disease in the retroperitoneum exposes patients to the risk of late relapse events with potentially lethal consequences. For patients with low-stage nonseminomatous germ cell tumor (NSGCT), primary RPLND is an important staging tool to define subsequent treatment requirements, simplify the follow-up of patients by obviating the need for routine abdominal imaging, and limit the exposure of patients to the long-term toxicity of chemotherapy. RPLND alone is curative in up to 90% of patients with low-volume retroperitoneal disease. In the post-chemotherapy setting, the inability to reliably exclude the presence of teratoma or viable germ cell cancer in the retroperitoneum mandates that post-chemotherapy RPLND be performed for all NSGCT patients with residual masses. With improvements in surgical technique and perioperative care, RPLND is associated with minimal short- and long-term morbidity in the hands of experienced surgeons at dedicated centers. This article reviews the role of RPLND in the management of patients with NSGCT at all stages and its role in advanced seminoma.

Abstract
PURPOSE We evaluated the prognostic parameters of necrotic residual tumors after chemotherapy of advanced germ cell tumors to improve on the current indications for surgery. MATERIALS AND METHODS Between January 1996 and January 2000, in 8 centers of the German Testicular Cancer Study Group, preoperative parameters were assessed to predict necrosis in the residual tumors of 261 patients with retroperitoneal residual tumor resection after first (92%) and second line (8%) chemotherapy. RESULTS Of 232 evaluable patients 39 had pure seminoma and 5 had viable cancer (1 with seminoma) in the residual tumor. Of the remaining 193 patients with nonseminoma 35% had necrosis, 34% teratoma and 31% had viable carcinoma in the residual tumor. After multivariate analysis and exclusion of patients with seminoma, the 3 parameters independently predictive of necrosis were alpha-fetoprotein before chemotherapy less than 20 ng/ml, and tumor volume before and after chemotherapy. A mathematical model to predict necrosis yielded a test accuracy of 75%, a sensitivity to predict necrosis of 52% and a specificity of 87%. CONCLUSIONS Patients with pure seminoma should not undergo residual tumor resection because 97% of patients who received adequate chemotherapy were found to have no residual seminoma. In cases of nonseminoma alpha-fetoprotein values before chemotherapy less than 20 ng/ml and a high percentage of shrinkage during chemotherapy reliably predicted only 19% of cases of necrosis. Therefore, this model is clinically irrelevant and patients with minimal residual disease should undergo surgery. New methods are necessary to improve the preoperative selection of patients after chemotherapy.
